This is the 4GB version.

Unfortunately, I am not familiar with how to get this information. If
you could provide some instructions for how to do so, I am more than
happy to. I am not very knowleagable about the inner working of the Pi,
I mainly use it as a test platform for making sure that LLVM does not
cause problems on real devices.

I have attached a working and broken boot log. Thank you for the quick
response!

Cheers,
Nathan
